By some convoluted route I have managed to update one of my 3.1.7-pl1 boards

I uploaded the 3.1.7-pl1 -> 3.2.0-b1 package, ran update and selected update database (although it did not update the version in the config table) and then copied the updated files from the 3.2.0-b1 files package.

That's due to the cache. If you are not in debug mode that's normal.
In a production mode a lot of things are done to optimize the application. And it also means that the cache has to be cleared every time you change something in an extension (it is done automatically when enabling/disabling an extension bu not when updating the board)

But I am not changing anything - just enabling an extension and then configuring it in the ACP. I know that purging the cache is done when enabling/disabling an extension so it seems strange that I have to purge the cache again. It never did this with 3.2.0.-a1/2
